The invention relates to an electrode system (200) that is particularly suited for deep brain stimulation. According to a preferred embodiment, the electrode system (200) comprises an elongated probe body (202) carrying a plurality of annular stimulation electrodes (201) of radius r and axial extension h that are axially distributed at distances d. The axial extension h is preferably smaller than the diameter 2r and preferably larger than the distance d. Moreover, the electrode system (200) optionally comprises a plurality of microelectrodes (203) projecting radially away from the probe body (202), said microelectrodes (203) being suited for recording neurophysio logic potentials. |
